Have you thought about trying Avatar?
They don't address force, mass or charge, but they do elicit a "feel good" factor, which may well be something you are looking for.
I know of a few Avatar Wizards and they assure me that people do get a nice, warm fuzzy feeling from their techniques. If you like you can PM me and I will give you a number to call.

I've met some Electricians and Physicists who deal with force, mass and charge.
Dealing with "force" is necessary when a person has been subjected to it. "Mass" I have no understanding of in a processing context. "Charge" I understand as "repressed, unfulfilled intention". I deal with that extensively.
